About this extension
Tools for Substack!

Features:
  • Note Filter: Hide notes from your feed based on certain words and phrases. Now you can finally get rid of all the Sabrina Carpenter spam! (New in v1.2.0)
  • Note Exporter: Save all notes you've ever posted into a single text file
  • Block Checker: See how many people have blocked you, for funsies

How to use:

Simply install the browser extension, and visit the Substack homepage. Once there, click the BlockedStack button on your toolbar to open it (it's a tiny pink snail), and try out the buttons. Most of these involve long-running operations, so you'll have to be patient while it does its thing.

Enjoy!
